The water current flows over the top of the dentoid baffle to the hydraulic jump as additional momentum . while it is cooperated with a stilling basin , the flowing condition emerged in the basin may be improved greatly and the length and downstream water depth required by the basin can be decreased to a great extent . such an appliance may be also used to solve the problems of insufficiently dissipating water flow energy and aerating flow , which are often faced with those hydraulic engineering constraction as acted by high waterhead , great specific discharge and low froude number 本文通过齿墩顶部的扩散水舌所形成的附加射流，从上部射入水跃，即可改善消力池内的水流流态，又可降低第二共轭水深，减小水跃长度，增进水跃消能效果，同时还能解决大单宽、低佛劳德数条件下掺气和消能不足的问题，试验证实它是一种安全、经济的消能工。
The paper analyses and compares the " factor effect on the flow in the pond by the numerical simulating software . the analysis shows the flow structures in the pond are not only related with the velocity of flow , angle of jet and the size of the entrance and so on , but also are related with the size of the pond 根据计算，论文对锥形阀消力池流态的影响因素进行了分析和对，比，分析认为，锥形阀消力池内的水流流态与入射水流的流速、入流t角度和进口尺寸以及水垫尺寸等反映淹没撞击射流的基本参数有关，也受消力池长度、宽度影响。
